Problems solved by technology

The invention utilizes permanent magnets to intermittently magnetize the multi-layer wire mesh medium plate to mix the magnetic particles evenly in the reaction chamber. Since the magnetic particles may gather on the surface of the wire mesh medium plate for a long time and the wire mesh medium plates with different distances from the permanent magnet are magnetized There is also a big difference in strength and weakness, the mixing effect may not be good, and the invention has a complicated structure and is not flexible for various processes, and does not involve the design of devices such as temperature parameters

Abstract

The invention discloses a bioreactor applied to magnetic nano-catalyst which has the structure that one end of a first shaft coupling is connected with an output shaft of a first motor and the other end is connected with a connecting disc; a reaction vessel is installed on the connecting disc, provided with an input pipe and an output pipe with valves, and is installed with a temperature control apparatus. In use, the magnetic nano-catalyst is arranged in the reaction vessel and is adsorbed on the wall of the reaction vessel by means of a magnet. The magnetic nano-catalyst is uniformly mixed and conveniently recycled and and has the advantages of improving the catalyst using efficiency, flexibility to different technologies and reducing pollution.

Description

technical field [0001] The invention relates to a bioreactor, in particular to a bioreactor for catalytic reaction using a magnetic nanometer catalyst. Background technique [0002] With the development of nanoscience and technology, it has been found that nanomaterials have many unique properties such as quantum size effect, small size effect, surface effect and macroscopic quantum tunneling effect, making them widely used in catalysis, lasers, magnetic media and new materials. prospect. Nanoparticles have a large specific surface area, have bioaffinity, and are easy to couple specific targeting molecules on their surface. Magnetic nanoparticles are ultrafine powders containing magnetic metals or metal oxides (such as iron, cobalt, nickel and their oxides) inside, and are magnetically responsive polymer microspheres. Magnetic nanoparticles exhibit good surface effects, with a surge in specific surface area, increased functional group density and selective adsorption capac...
